Owls boss Stuart Gray has said he expects a tough battle at Millwall on Tuesday evening at The Den.
The Lions are fighting for Championship survival and are three points adrift from safety.
Gray expects a tough battle on Tuesday but has urged his side to take the positives from the weekend trip to Derby down to South East London.
He said: “They are down there fighting and scrapping, but we have got to build on the performance we gave at Derby.
“I was looking for a reaction after being poor at Ipswich and there were positives we can take from the game.
“Derby are top of the league, we’ve given them a good game and we have to make sure we turn up on Tuesday.
“Any game you go to at Millwall, you have got to be prepared, mentally right and physically ready for the challenge.”
While Millwall are searching for their first home win since October, priority for Wednesday is to halt the run without a win and Gray added:
“We are without a win in our last seven and that’s a stat that doesn’t lie but there are still a lot of points to play for.
“For progress, I think we have got to finish higher than what we did last season. I’m a great believer that you have to tick every box better than last season.
“At the moment we haven’t scored enough goals, defensively we are doing ok but ultimately, it’s about where you finish at the end of the season in terms of your league position.”
